RHD2000 LabVIEW Library


The RHD2000 LabVIEW Library links the RHD2000 Evaluation System to National Instruments' powerful LabVIEW software.

The library contains Virtual Instruments (VIs) that enable live control of electrophysiology data acquisition using the RHD2000 USB interface board and associated amplifier boards. The intuitive, graphical programming used in LabVIEW allows for quick and easy development of data acquisition software tailored to specific applications.

Joining the RHD2000 Evaluation System with LabVIEW allows for seamless integration with other laboratory instruments. The Intan LabVIEW library contains easy-to-use virtual instruments for basic data acquisition and configuration VIs when advanced control is needed.  Specialized VIs support electrode impedance measurement, streaming data to files, and other commonly used functions.

The RHD2000 LabVIEW library includes many pre-made examples to serve as tutorials and to jump-start development.

Pre-made examples include:

  • Acquiring, displaying, and streaming electrophysiology data to disk in real time
  • Performing real time analysis on amplifier waveforms: implementing a virtual reference, isolating spikes and LFPs, and counting spikes
  • Implementing episodic recording: automatically saving separate files for multiple trials demarcated by a digital input
  • Controlling multiple RHD2000 USB interface boards from one computer for acquiring more than 256 channels of data.
  • Measuring in situ electrode impedances

Download

System requirements: LabVIEW 2010 or later, 32- or 64-bit, running under Windows. (If you are interested in a different version, please contact us.)

Download version 1.1.1 (45 MB) (updated Jan. 26, 2015): RHD2000 LabVIEW library with 45-day trial license. (Release notes)

The download, a LabVIEW VI Package Manager file, will install the Intan library and add a new block diagram palette under Instrument I/O -> Instr Drivers -> Intan RHD2000.  We recommend starting from the VI Tree on the Intan RHD2000 palette, opening the VI Tree’s block diagram, and running the examples at the top.  Each example contains extensive documentation in the form of comments, and Context Help is available for all examples and library VIs.

Please verify the integrity of your download before running the installer.  In some cases the file is only partially downloaded.  The expected size of the file intan_rhd2000-1.1.1.3.vip is 46,020,554 bytes. For additional security, you may wish to verify the hash of the download.  The MD5 Hash of the vip file is B5940B11F22F99637B6B3EFB4526C8F9.  (You can download a free tool from Microsoft to verify hashes here.)

Installation Notes:

If you have not already installed the RHD2000 USB interface board drivers, these should be installed prior to using the LabVIEW library.

As part of the install, several dialog boxes pop up, and they are sometimes blocked by other windows.  For that reason, we recommend that you close all other programs before installing the Intan RHD2000 LabVIEW Library, and that you look for hidden windows if the installer pauses for 30 seconds or more.

The library itself is compatible with LabVIEW 2010 and higher. However, the installer was created with the 2014 version of the VI Package Manager.  You'll need to upgrade your VI Package Manager to 2014 if you get the error message "This package is not compatible with any LabVIEW version on this computer". Look here for more information.

Licensing

A perpetual license may be purchased directly from Intan Technologies.  The perpetual license uses a USB key and can be moved between different PCs for convenience.  Pricing information is listed here.

The operation of the RHD2000 USB interface board and amplifier boards are described in more detail in the RHD2000 evaluation system datasheet. All components of the system are shown in the RHD2000 evaluation system catalog.
